    This work discusses the research conducted to develop an appropriate agent to enhance the anti-fungal properties of water hyacinth stalks, which are commonly used in handicraft products in Thailand. The objective of the research was to find an agent that would prevent fungal infestations, prolong the shelf life of the products, and ultimately increase the income for the craft makers. The initial experiment involved treating cotton fabrics with three different antifungal solutions: Chitosan, Zinc Pyrithione, and Poly (allylamine hydrochloride). These treated samples were then tested with Aspergillus niger, a common fungal strain, using the standard antifungal test AATCC 30. Among the three finishes, the fabric treated with Poly (allylamine hydrochloride) displayed the highest anti-fungal properties. However, the fabric treated with Zinc Pyrithione effectively inhibited fungal growth but left visible white particles on the fabric. Chitosan, on the other hand, did not significantly inhibit fungal growth. Based on these test results, it was concluded that a solution of Poly (allylamine hydrochloride) can be employed as a finishing agent for water hyacinth to enhance its antifungal properties in water hyacinth-based products. Additionally, it was found that a higher concentration of Poly (allylamine hydrochloride) (100 g/L) is necessary to effectively prevent fungal growth on water hyacinth stalks. By utilizing this research, local Thai communities can enhance the durability and longevity of their water hyacinth handicraft products, reducing the impact of fungal infestations and increasing their income.
